A selection set is only valid if all fields (including spreading any
fragments) either correspond to distinct response names or can be merged
without ambiguity.
The algorithm is described in CachedCheck.
The validation rule implements the same validation as OverlappingFieldsCanBeMerged
and could eventually replace it. It is an alternative, more performant implementation.
